How Many T5s?

[Mitchell0605]

Hey guys,
How many T5HO's would you need over a 4'L x 18"W x 20"H mixed reef?

At least 4, but 6 would give you more choices in corals.

I was going to suggest 6 as well.

What kind of Kelvin temp? I was thinking two 10000K, 1 5500K at the back (higher aquascape and light for SPS) and a 17000K at the front, for blue colour.
